Optional fail init command when no project id is provided

So, in our current setup, in CI, we're doing a awsmobile init -y $PROJECT_ID on each deploy but if no project ID is provided in $PROJECT_ID a new project is being initialised in the AWS MobileHub.

I think it would be a nice option to allow awsmobile init to fail if no project ID is provided instead of creating a new project.

init without projectID covers other use cases in which developers need to quickly setup the cloud backend for their frontend project, so it should not fail.
